REINFORCED CONCRETE FLOATING STRUCTURE.

Specification of Letters Patent. Patented Paar; 15 1921 Applicationfiled February 7, 1920. Serial No. 357,010.

reinforced concrete floating structures, such as barges, scows, ships,etc, and has for its object to provide an improved, strong, light,buoyant structure of this nature that can be produced at low cost.

An important novel characteristic of the invention resides in thespecial use of tubular reinforcin elements,the particular manner ofinterlocking the same in the concrete body and sealing the ends thereof,and their connection together.

Important features of the invention also lie in the special reinforcingframes provided, and the particular association and arrangement thereofwith the tubular reinforcing elements, whereby great strength andload-carrying capacity is combined with lightness, and the structure canbe easily and quickly built in courses.

The invention, with other objects and advantages thereof and theparticular construction, combination and arrangement of parts comprisingthe same, will be understood from the hereinafter contained detaileddescription when considered in connection with the accompanying drawingsforming part hereof and illustrating one embodiment of the invention.

In the drawings:

Figure 1 is a top plan View with parts shown in section of one endportion of a,

barge constructed .in accordance with the present invention.

Fig. 2 is a transverse section.

Fig. is a transverse section on an enlarged scale through one side ofthe construction. 7

Figs. 4; and 5 are detailed views of the connections between certain ofthe frame members.

Fig. 6 is a transverse section on an' enlarged scale through a portionof the bottom.

Figs. 7, 8, 9, 10, 11, 12 and 13 are detailed views of certain parts ofthe construction.

The invention comprehends a hull for boats, barges, ships and the likeconstructed of concrete, with its walls largely formed hollow, andhaving rows or series of closely associated tubular reinforcing elementsembedded in the walls thereof. Associated with the rows of tubularreinforcing ele ments. are rows or sets of transverse and longitudinalreinforcing rods located adja cent opposite side faces thereof, and atin-. tervals along the tubular reinforcing ele ments., are providedframes extending from side to side of the structure. I reinforcingelement is made up of sections arranged end to end in spaced relationwith portions of the concrete of the walls extend ing a short distancewithin the ends of the tubular sections, the transverse frames beinglocated in the spacesbetween the ends of the sections of the tubularreinforcing elements. connected. together and partially embedded in theconcrete bottom and side walls, serve to reinforce and trussv thestructure transversely, and also as means for positioning and supportingthe other reinforcing elements during the building up process.

The present applicationis to be considered as a continuation of myapplication Serial No. 226,179, filed April 2, 1918, in so far as thesubject matter is common to the two cases. i i

In the drawings, the invention is shown embodied in a barge structurehaving a botgunwale portions 45 along the sides and ends. 7

6 and 7 designate, respectively, the tubular reinforcing elements of thebottom and sides,

and 8 those of the ends, the former extend-' of sections arranged inlongitudinal alinement in separated relation with end portions 7 thereoffilled up and sealed from each other by portions 6 7 of the concretewalls. The sections of the tubular reinforcing elements 6-7 areconnected together by The transverse frames, which are Each of thelongi-v tudinal reinforcing elements 67 is made up- Each tubular '90 tomwall 1, side walls 2, end wells 3, and

rods 9, said rods having their ends embedded in the portions 6 -7 of theconcrete walls and connected with plugs 10, of wood.

or other suitable material, positioned within the tubular elements.Similar connections 1 ments 6-7are grouped, as shown, to leave spacesbetween the ends thereof extending completely across the bottom 1, sidewalls 2,

and gunwale portions 8. At intervals along the longitudinal tubularreinforclng elements 6-? at the spaces 11 between. the ends of thesections, transverse frames are provided. The transverse frames areshown composed of pairs of lower horizontal channel bars 12 extendingacross and embedded in the bottom wall 1, pairs of vertical L-bars 13 inthe side walls 2 secured at their lower ends to the ends of thehorizontal channel bars 12, upper horizontal angle bars 14' se cured attheir outer ends to the upper ends of the vertical L-bars 13, andinclined truss members or struts consisting of pairs of angle bars 15extending from the inner end portions of the upper horizontal bars 14 tothe lower channelbars 12 intermediate the ends thereof, the connectionsbetween the members being made by suitable tie plates 1.6-1.718 andupper horizontal strips 14, the parts being secured by rivets, bolts orthe like, 19 as shown. 20, 20" and 2i designate gusset plates to whichare secured inclined and horizontal braces 23--2 l.

lower l'lOI'lZOlltdl channel members 12 and The vertical bars 13 areprovided with rows of apertures B a-13 to accommodate the in termediateconnectlng rods 9, said rods exl tending through the apertures in thebars from one group of tubular sections to another.

Extending between the transverse frames and connecting the same togetherat their bottom parts are intermediate L-bars 25, said bars beingpartially embedded in the bottom wall 1 and connected at opposite endsby tie plates 25 with the horizontal channel bars 12 of the transverseframes. 26,. 27 and 27 designate respectively intermediate L-bars, thebars 26 connecting adjacent channel bars 12, the L-bars 27 being securedat opposite ends to the top portions 4 at the inner sides thereoflandthe Lbars 27 being disposed about midway the top and bottom of theframes and secured at oppositelends to horizontal braces 24. 33, areangle braces between the horizontal bars 27, 27 and 28, 29 designateangle bars extending longitudinally between the frames at the outercorner portions of the structure, suitable tie plates 30 being providedbetween these parts.

Associated with the rows of tubular reinforcing elements 6, 7 and 8, inthe bottom, sides, ends and gunwale portions are series of longitudinalreinforcing rods 37, and transverse reinforcing rods 38, the sets ofreinforcing rods being embedded in the walls at the sides of the rows oftubular reinforcing elements. The longitudinal reinforcing elements 37are made in sections and arranged so that the end portions of adjacentrod sections overlap at one side of the ad jaoent frames, and areconnected by wrappings 37 of wire, as shown, (see especially. Fig. 18 ofthe drawings). The sets of re iniorcing rods at opposite sides are connected by tie wires 39, and the lower set of longitudinal rods 37 isconnected with the rods 9 by wire ties 30, the upper set of rods 37extending through openings in the channel bars 12, and the lower set oflongitudinal rods 37 extending beneath the channels 12. On the inclinedstruts are arranged 'afters 4L0, and secured thereto and upon theinclined struts are floor boards 41. 42 designates flooring extendingover thebottom and across the channelbars 12.

, in the building process, two or more of the transverse frames,connected together,

are set up upon temporary supports with a ten'iporary platform of.boards at the umler sides of. the frames. The tubular reinforcingelements 6 and the sets of transverse and longitudinal reinforcing rods3?--- t-i of the bottom are first laid in 1;. cc, and the concreteforced in and permitted to set in and about the same, and the horizontalchannel bars 12 and intermediate connecting L-bars 25. In the laying thehorizontal channel bars 12 and l..-bars 1 :3. 'The sides, ends andgunwale portions ti e are then built up in courses in like By thespecial construction and arrangeinent ofparts hereinbefore described,alight buoyant structure of great strength and requisite strength. Theportions of the concrete walls entering the ends of the sections of thetubular elements not only'prothe building process, insuring the uniformdistribution thereof throughout the completed structure.

Nhile I have illustrated in the drawings, by way of example, a preferredembodiment of the invention, it will of course be understood that minorchanges and variations in the particular constructionshown, and thecarrying out of the invention in the other forms as will appeal to thoseskilled in the art and falling within the scope of the appended claims,may be practised without departing from the spirit of the invention. Inthis connection, it will be understood that different forms of anglebars may be employed, that the tubular reinforcing.

elements may take other forms and be of different lengths, and that thenumber of transverse frames maybe varied to meet different conditions. 7
